Problems solved by technology

However, in a limited area, there are usually multiple users, even reaching the requirement of thousands or tens of thousands of users accessing at the same time. Increase the number of access users and the number of programs at the same level, so it seems powerless
Although the bit error rate can be reduced by increasing the bandwidth, thereby reducing the probability of system communication retransmission, it is heavily dependent on bandwidth resources

Embodiment Construction

[0042] The technical scheme of the present invention is as follows: firstly, after the video data stream is processed by error correction, marking, self-adaptive grouping and interleaving in the multimedia network synthesis processor, the data stream is encapsulated according to the frame format of 802.11. The encapsulated data packet is determined by the destination address related to the broadcast transmission mode, and this address is the broadcast address pointing to the subnet. Finally, the video multi-program IP packet data stream is broadcasted on the broadcast address and port. In this way, a large number of common user terminal APPs can receive the video data transmitted from the broadcast port. see figure 1 . Specifically, a method for broadcasting and transmitting multi-program video streams based on WiFi includes the following steps:

[0043] Step A, distribution processing of multiple program data streams.

[0044] What we are dealing with is a multi-program v...

Abstract

The present invention discloses a WiFi-based method and apparatus for broadcasting, sending and transmitting multiple program video streams. Firstly, a video data stream is corrected, marked, adaptively grouped and interwoven at a multimedia network synthesis processor; then the data stream is encapsulated according to a 802.11 frame format; an encapsulated data packet is determined according to a destination address associated with a broadcast transmit manner, wherein the address is a broadcast address pointing to a subnet; and finally, IP packet data streams of multiple program videos are sent at an address and a port of the broadcast in a broadcasting manner, so that a lot of common user terminal APPs can receive video data transmitted from the broadcasting port. Through adoption of the method, a great deal of users can access the system simultaneously in a limited range, further, high-definition videos can be ensured to be transmitted and played.

Description

technical field [0001] The invention relates to the technical field of multimedia information dissemination, in particular to a method and device for broadcasting and transmitting multi-program video streams based on WiFi. Background technique [0002] Since the existing wireless WiFi communication system generally can only accommodate the video data transmission of less than 32 users at the same time, in the process of data transmission, there is often the problem of multi-user competition for the channel, which makes it impossible to meet the transmission of multi-user high-definition video data streams . With the increasing demand of mass consumption, this simply cannot meet the demands of multi-user multi-program transmission and playback of high-definition video at the same time. [0003] To solve this problem, the method adopted at present is to manage user channel competition and reduce interference between users. This method needs to reduce interference from the al...
